Still looking for sexual advice?

First of all I feel that I need to point out that my husband and I have a shared E-mail address. Secondly I wish to thank those that took the time to try and help with my last question. As I pointed out before I am a 49 year old woman that's been happily married to the same man for almost 30 years,and in that time on occasion he has tried to get me interested in trying anal sex, though I've never really had any interest in it myself,to be frank the idea of having his manhood jammed up my backside just made me a little uncomfortable, but recently I have been giving the idea some thought. What I would like to know is how to approach my husband with the idea without him getting to overly excited and either ruining the moment or worse yet hurting me? I would also like advice on the art of deep throating I already enjoy preforming orally on my husband but I have never been able to get more than an inch or two in my mouth what might I do to be able get all of his organ in my mouth?
